See attached picture.
Use a incandescent 120V, 60W lamp in series with the mains input as a current limiter. If the lamp glows brightly when you apply power, your short remains.
If it pulses bright and goes dim, then you (likely) have solved the short.
Attached image shows a 100W lamp (0.83A @ 120V). Better to start with the 60W if you can (0.5A @ 120V). Use the correct voltage lamp for your mains.
My suspect in this would be the blue 2n2, 2kV cap and that it is shorted. (0.0022µF)

This kind of power supply don't work with such a current limiter.
To oscillate, voltage upon R1023 and R1024 must be higher than 1.2V, that's mean that the current must be higher than 2.4A to trigger V1014 (BRY62).
With a current limiter, this value of current will not be reached and the power supply will never oscillate.
The lamp will stay fully on even with a good working power supply.
The lamp current limiter is useless with this kind of power supply.
If you want to test this power supply safely using a 100W 240V current limiting lamp, You should remove R1023 and R1024 and replace them by one 5.6R resistor.
You will be able to check as the power supply is oscilating or not.
NB: with this modification, the power supply will oscilate at more or less 200Khz, that's far too high frequency.
To lower this frequency, change value of C1011 from 47nF to 470nF.
Power delivery with these modifications is very low and it will work as an heavy overloaded flyback converter.
Output voltages will be very low, that's normal.
